Bound residue
WebBound Residue: Residues derived from the covalent binding of the parent drug or a metabolite of the drug and a cellular biological soluble or insoluble macromolecule. These residues are not extractable from the macromolecule by exhaustive extraction, denaturation or solubilization techniques. WebAided Studies of Bound Pesticide Residues in Soil, Plants and Food, in December 1981, the following definition of BR was adopted: "Nonextractable (bound) pesticide residues in soils, plants and food are chemical species originating from pesticide usage that cannot be extracted by methods commonly used in residue analyses and metabolism studies."
